Check these first
- Check if the soil is waterlogged or smells sour.
- Move the plant to a brighter location to see if color improves.
- Inspect the roots for any signs of decay or dark color.
Likely causes
Poor Drainage
Most likelyHow to tell: The leaves turn yellow and the base of the plant feels mushy. This happens when the roots are sitting in water for too long without oxygen.
What to do: Repot the plant into a container with better drainage holes. Use a potting mix that holds moisture but does not turn into mud.
Insufficient Light
PossibleHow to tell: The leaves turn a pale yellow and the plant looks weak or stretched. This happens when the sedge is kept in a dark corner away from bright light.
What to do: Move the plant to a location with bright indirect light or partial sun. Ensure it gets at least 4 to 6 hours of light daily.

Stopping it coming back
Provide bright light and ensure the soil stays moist but not soggy.

Questions people ask
- Does my sedge need fertilizer?
- If the yellowing is uniform and the plant is not growing, a balanced liquid fertilizer applied once a month during the growing season might help.
- Can I leave it in standing water?
- Yes, it tolerates wet soil and even shallow standing water, since it naturally grows in swamps and wet meadows. Just keep the water fresh rather than sour and stale so the roots can breathe.
